Open mode failure An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit. For example, if a large capacitor is used in the smoothing circuit of a power supply, a large wave-like voltage *4 can be converted to a flat DC voltage, but if the capacitor is open, a large voltage wave is …
Refrigerator Compressor Running but Not Cooling
Check the fan blade for physical obstructions Rotate the fan by hand. If it doesn''t spin freely, replace the motor. If it spins freely, test the motor for continuity.Replace the condenser fan motor with a new one if the continuity test fails. The evaporator fan draws air over the cooling coils and circulates this air within the fridge and freezer compartments.
LED Lights Flickering or Strobing? 6 Common Reasons
Flickering of LED lights could be very annoying. LED bulbs and headlights can flicker in many situations. Sometimes a dimmer switch is involved, other times the flickering happens due to other technical reasons. In this article you will learn the root causes of LED

What Causes Capacitors to Fail?
If You''re Like Most People, You Probably Don''t Think About Capacitors Very Often. But if You''ve Ever Had One Fail on You, You Know It Can Be a Big Problem. There are two main reasons why dissipation factors can cause capacitor failure. First, if the dissipation factor is too high, the capacitor will overheat and eventually catch fire.
Why Your Capacitor Bank Should be Left Ungrounded
Background In general, most industrial facilities with 2.4kV through 13.8 kV distribution are resistive grounded through a grounding resistor as shown in Figure 1. The systems are resistive grounded to reduce the fault current and arc damage during line to ground
What Causes an AC Capacitor to Fail?
A capacitor is a small, cylindrical component that sends energy to the motor that powers the air conditioning system. It''s located inside the outdoor unit, also called the condenser, and can lose its efficiency with day-to-day wear and tear. In this article, HVAC replacement company Stone Heating and Air shares the common reasons for AC capacitor failure …
